I decided after the T 12 lights in my attached garage started having
problems to replace them with T8's.(Electroonic ballasts) Since doing
this, Channel 5 WTVF goes out every time I turn the garage lights on.
It goes back to normal when the lights are off.

I have a rooftop antenna a yagi, on a tower right outside my garage. I
also have on this tower my dish network dish.

I origionally thought it was probably the light and replaced it with
another one from Lowes, but this light did the same thing as well.

Is there a way to diagnose what is causing this or preventing it?

I also have UHF little antennas at varios tv's in the house to be able
to work the remote from another bedroom. (Satelite box). however, for
a test, I unscrewed one of the antennas at the kitchen tv and it made
no difference.

The remotes work at 2.4Ghz, well within the microwave spectrum. *A
leaky microwave oven will affect those, not much else.

If the ballasts are putting out that much RFI, you should be wiping
out AM reception for quite a ways, a cheap transistor radio should
pick that right up. *If they're chink fixtures, not much you can do
except replace them with something better-made. *Another problem,
maybe easier to fix, would be that the ballasts aren't radiating but
putting out a signal down your AC power lines and that's getting into
your electronics that way. *RF chokes and filters can be added to kill
that off, shouldn't have to be done on correctly designed ballasts,
but would be a possible fix. *I had a chink-designed motor control
that tripped the computer's UPS anytime I used it, had to stick an EMI
filter on the power cord to kill that.

Thing is, I took one light back to lowes and exchanged it and now this
light does it too. It is the commercial stip lights I bought. I really
dont want to buy another ballast. And chennel 5 here is broadcast on
VHF.

Is there a filter I could install on the coax of the antenna?
